As summer begins to wind down and we ease into the cooler days of fall, many homeowners in New England breathe a sigh of relief thinking mosquito season is almost over. Unfortunately, the mosquitoes haven’t gotten the memo. Late summer and early fall are still active breeding times for these persistent pests, and depending on the weather, mosquito season in New Hampshire and Massachusetts can stretch well into October.
If you’re still swatting at mosquitoes on your patio or avoiding your backyard altogether, now is not the time to let your guard down. At Cornerstone Pest Control, we specialize in late summer mosquito control treatments to help protect your family and reclaim your outdoor spaces for the remainder of the season.
Are Mosquitoes Still Breeding in Late Summer?
Yes—mosquitoes are still breeding. In fact, warm and humid late summer conditions create a perfect environment for mosquito reproduction. Female mosquitoes lay their eggs in standing water, and those eggs can hatch in as little as 24 to 48 hours under the right conditions.
Birdbaths, clogged gutters, old flowerpots, and even puddles hidden under decks can serve as breeding grounds well into the fall. As long as temperatures remain above 50°F, mosquitoes continue to bite, breed, and multiply.
When Does Mosquito Season End?
In New England, mosquito activity typically declines when we experience our first few consistent nights below 50°F. For many areas, this doesn’t occur until late September or even mid-October. However, that timeline can vary depending on the year’s weather patterns.
It’s also worth noting that some mosquito species—like Culex pipiens, which can transmit West Nile virus—tend to remain active longer into the fall. This makes professional mosquito control an important part of your late-season outdoor care.
Why Late Season Mosquito Control Still Matters
You may think mosquito treatments are only necessary in spring and early summer, but late-season control is critical for several reasons:
- Ongoing Breeding
Every untreated property allows mosquitoes to lay eggs that can hatch quickly and spread. Treatments help disrupt the reproductive cycle and reduce future populations. - Health Risks
Mosquitoes are more than just a nuisance—they’re also disease carriers. Cases of West Nile virus and Eastern Equine Encephalitis (EEE) have historically peaked in late summer in the Northeast. - Fall Activities
Late summer and early fall are prime times for cookouts, bonfires, and other outdoor gatherings. Don’t let mosquitoes drive you inside.
